Windows activation, at least for 2008 and below, depend on enough hardware
changes to happen. Each HW (of non-pluggable devices) change is a single
'penalty' point - except for NIC (based on MAC address) which is more. 4 or
so points - and it requires re-activation. This does not apply to KMS
licenses.
So unless you drastically change the hardware, you should be safe.

Hello,
Most of our virtual machines are Linux, but an increasing number of
windows VMs are being integrated into our oVirt DCs.
We bought tons of windows server licences, and successfully activated them.
Due to how Windows Product Activation is working, when a windows VM is
migrating from a host to another, this product activation is reset,
launching a 30 days countdown to auto-shutdown.
According to this old page :
https://mazimi.wordpress.com/2007/07/11/getting-around-windo
ws-activation-when-virtualizing/
and what I can read in microsoft's 2012 server documentations, I then can
re-activate it twice during the next 90 days.
Assuming I *want* to have *no* control upon the location of the VMs
amongst their hosts (I want them to fly freely, confident in the lovely
auto-balance scheduler), I understand all this is not the way to go.
At present, we have 2003, 2008 and 2012 server editions.
the only things I can read about windows 2012 server is related to the
commercial aspects (standard licence = 2 VMs, datacenter licencce =
infinite # of VMs), but not about this Windows Product Activation trouble.
How do you deal with this?
Is there a special licence type or something dedicated that would prevent
such an uncomfortable situation? (Christmas is near, I favor soft terms.)
Regards.
